Ducato blankety blank

Obviously this question has no connection to my previous long winded description of the throttle body replacement and ensuing lumpy tick over problems. Merely asking for a friend. If this friend was to fit a blanking plate for the egr can it be fitted next to the throttle body which looks easy or does it have to be adjacent to the egr valve? The egr is the vacuum operated one with the electronics going to the vacuum valve just under the bonnet.

I understand you can just block the vacuum pipe from the controller to the valve but if the valve was stuck slightly open this would not cure the problem.

Anyway any info would be appreciated ……

However you do it it will need deleting from the ECU or a fault light will be shown and a fault code on the OBD

Also be aware that You may need to amend the ecu set up to accommodate the change.
you could get the dreaded engine warning light on if you don’t, which is going to highlight a problem to any mot tester.

Not sure about that as it is “dumb” downstream of the vacuum control valve which can be left connected. The management can keep talking to the controller but has no idea after that.

I guess it depends on the age of the motor as to what is fitted and what the ecu will want to control.
Is Your “friend “ sure that the ecu will ignore the fact that the vacuum valve will no longer sense any changes.
If he is then good luck.

I have fitted an ERG blanking plate to our 2013 Elddis on a Peugeot Boxer 2.2 Puma engine with no problems.
The ERG blanking plate I fitted has a hole in it, about 8mm diameter, to let enough exhaust gas through to keep the sensor happy and not throw up any fault codes.

I'd clamp the vac tube and see if the ECU is happy, and take your next step from there.

I'm not technically minded, so why would you want/need to do this?

On our van, it gives improve throttle response and acceleration, and better engine performance by reducing the recirculation of the burnt exhaust gases that have no fuel left to burn to give combustion on the power stroke. It's much the same as EGR delete on an ECU remap.

I have the same engine as you, do you have a link for the EGR plate and did it come with the hole in it?

I bought mine from this eBay seller, and yes, it did come with the hole in it.

It's a bit fiddly to fit (lack of space to work in). I did it from under the van, loosening the bolts on the pipework and slipping it into place without actually removing anything.

EGR Valve Restricter plate Fiat Ducato 2.2L 100 Multijet 2,198cc blank S/S H | eBay

2006 on- Fiat Ducato 2.2L100 Multijet PUMA engine (2,198 cc ). Will not fit the 2,287 cc as it is a Sofim engine. Prevents soot build up in intake manifold, and valve's, which will lower the power. DPF/FAP regenerates less as there is less soot to trap if one is fitted.

Well I never…. By simply plugging the feed vacuum tube to the control vacuum valve I effectively isolated the egr valve. The van was then much nicer to drive and felt far more responsive, however the hunting on tick over was still there! I then re-inspected the hard plastic pipe that draws (!) the vacuum from the pump/ brake servo line to operate the egr valve via the vacuum valve. I noticed a small chaffing in one very inaccessible area so just managed to wrap one bodge tape around it. Hallelujah the hunting stopped and tickover was steady! Wiggled the pipe and it started again, restock the bodge tape and it stopped.

Soooo…. Now going to replace the hard plastic vacuum pipe but will probably leave the vacuum valve isolated from the vacuum pipe but leave the electrical connection. As I said the van felt far better to drive with the only very slight negative being an occasional run on for one firing when turning the engine off as apparently the egr valve controls that as well. As yet no sign of a fault code as the mechanical side of things is downstream of the electrical inputs on the vacuum control valve and as such there appears to be no feed back to the emu. Remember this is a 2009 2.3 which is pre electrically operated egr.

As I say, every day is a school day…….

I fitted blanking plates to both ends of the EGR cooler. Only one end would need to be done to get the same result, but I’d prefer to sort it best I can. If you just physically blank the EGR the ECU will close the throttle body, when it wants the EGR to be used. This will starve your engine of air. So I had mine mapped out of the ECU. An alternative if you have the later TB is to remove the buterfly flap in the TB and blank the EGR. The engine is dumb to the EGR.

I put a short length of heat shrink tube over a split in my vacuum pipe. Still going strong 6 years later.
